The survival crafts 5 being configured to be stored in the storage unit in a deflated state as seen in FIG. 1 . For allowing the deflated survival crafts 5 to be deployed from the storage unit 2 a port 6 is arranged at the side of the storage unit 2 facing the water side of the vessel 1. In the present embodiment the port 6 is hinged to the bottom of the storage unit 2 so that during deployment the port 6 may be moved to the open position by turning the port 6 around the hinges whereby the port 6 is turned approximately 180 degrees in relation to the closed position of the port 6. The open position is shown in FIG. 1 . The storage unit 2 also comprises one or more doors for providing access for crew members to the inside of the storage unit 2. In addition, an area of the storage unit may be a technique room wherein different components of the maritime evacuation system 100 may be controlled and serviced.

Furthermore, each survival craft 5 comprises at least two engine powered propulsion means facilitating maneuverability of the survival craft 5 when inflated.

In FIG. 2 the survival crafts 5 are being deployed. The deflated survival crafts 5 are stored on a yoke 8, which also is stored inside the storage unit 2. The yoke 8 is configured to be moved out of the storage unit 2 during deployment and be lowered into the water with the deflated survival crafts 5. In FIG. 2 the yoke 8 and deflated survival crafts 5 are displaced out of the storage unit 2 by use of a deployment system 9.

In the present embodiment the evacuation system 100 comprises four survival crafts 5 which all are supported by the yoke 8. In other embodiments the maritime evacuation system 100 may comprise two, three or even a higher number. Each survival craft may have a capacity of more than 150 persons, preferably higher such as more than 200 persons.

In addition, the storage unit 2 may also comprise evacuation chutes 10 so persons may be evacuated from the vessel to the inflated survival crafts 5 when deployed into the water.

In FIG. 3 the storage unit 2 is shown without the yoke and deflated survival crafts. In the opposite side in relation to the port 6 the storage unit may comprise doors 11 which provide access to chutes when the survival crafts have been deployed.
